You are correct about the Leslie Ann Warren version,
but the Rodgers & Hammerstein "Cinderella" was actually first written
especially for
Julie Andrews in a TV presentation in 1957.
At that time, it became the single most-watched TV show in history!
(It's interesting to note that both Julie Andrews and Lesley Ann Warren also have a major connection to Disney musical films.)
Julie Andrews was presented at a darker-haired Cinderella, as well.
